Modular Cylinder Lock Assembly for Smart and Manual Operation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing smart locks with hotel functionality require a key to be permanently inserted in the inner cylinder, preventing manual locking or unlocking from the outside, and conventional locks are difficult for individuals to adjust to fit different door thicknesses without extensive disassembly.
Innovation Solution
A cylinder lock assembly comprising an inner and outer lock housing, a carrier with hotel functionality, and adjustable lock housing extensions that allow for simple length adaptation to fit various door thicknesses, enabling both manual and smart operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If a set-up unit is provided with a key permanently inserted in the inner cylinder, then the lock can be operated as a smart lock, but it becomes impossible to rotate the outer cylinder for manual locking or unlocking from the outside
Solution Approach 1:
The carrier coupling is designed to dynamically change its state between coupled and uncoupled conditions based on key insertion. When a key is inserted into the outer cylinder, the carrier coupling engages to transmit rotation from the outer cylinder to the carrier, enabling manual operation. When no key is inserted, the carrier coupling disengages, allowing the inner cylinder to rotate independently for smart lock operation.
2Ease of operation
If conventional cylinder locks are used, then manual locking and unlocking is possible, but the lock cannot be easily adjusted to fit different door thicknesses without extensive disassembly
Solution Approach 1:
The lock housing is segmented into multiple extension parts that can be selectively attached to the inner lock housing part. These extension parts come in different lengths, allowing the overall lock length to be adjusted to match various door thicknesses. The extensions are designed to be easily attachable and detachable without requiring disassembly of the main lock body.
3Adaptability or versatility
If the lock length is made adjustable to fit different door thicknesses, then adaptability improves, but the lock requires extensive disassembly for adjustment
Solution Approach 1:
The lock housing is divided into a base inner lock housing part and multiple separate extension parts. Each extension part is designed with attachment features that allow them to be independently added or removed from the base part. This modular segmentation enables length adjustment through simple attachment and detachment operations without requiring disassembly of the entire lock assembly.

AI summary
A cylinder lock assembly for forming a cylinder lock for attachment in a panel, such as, for example, a door, includes an inner lock housing part, an outer lock housing part, at least one bridge, a carrier, an outer cylinder, an inner cylinder, a carrier coupling, an operating knob, and a set of lock housing extension parts. The cylinder lock includes a selection from the set of the lock housing extension parts connected with the inner lock housing part in order to obtain a desired length of the inner lock housing part with the lock housing extension parts. This desired length is adaptable by changing the number of lock housing extension parts within the selection and/or selecting a lock housing extension part of a desired thickness. The selection from the set of the lock housing extension parts is positioned between the inner lock housing part and the operating knob.
